1) Why do you need it? You probably should have researched what LTE bands you wanted before buying a specific LG V30 variant? They're not all identical.
2) You can unlock your bootloader, root your phone and flash the AT&T H931 TWRP flashable zip.
https://forum.xda-developers.com/lg-v30/development/lg-v30-att-h931-20f-rom-t3872926
The H931 firmware has LTE band 40 and is compatible with US998. See attached screenshot.
However, normally only AT&T customers want/need that H931 firmware. Are you an AT&T customer?
AT&T doesn't release public KDZ, so you can't Frankenstein directly to H931. But you can use the most recent Oreo H931 TWRP flashable zip made by dev.
Do you realize this is the Moto X4 forum?
Oh haha sorry i don't know

Maybe a bit of a noob question but I just want to make sure. Does every single version of the Atrix HD sold (AT&T, T-Mobile, International) support all three of these:
AT&T 4G
AT&T HSPA+
T-Mobile HSPA+
Unlocking
Rooting
Thanks!

The Atrix HD on AT&T (when SIM unlocked) has working HSPA+ on T-Mobile, I am using it now. You cannot unlock it's bootloader, but you can root it thanks to Djrbliss.

Thanks! Some more questions:
Is it possible to SIM unlock yourself once you have achieved root?
What is the jellybean leak people are talking about? I thought one cannot install custom roms if you cannot unlock the bootloader?
And, if no way to install a recovery, how do you recalibrate your battery when required? The play store app? Which one exactly?

I have only seen (and have) the AT&T Atrix HD and I know Bell has it in Canada. Can you post references to a T-Mobile or international Atrix HD?

Way too many questions that are answered
AT&T model has a Jellybean leak, read about it in the threads.
You can install custom rom(s) through Safestrap Recovery 3 by Hashcode. It doesn't require an unlocked bootloader, just root.
I don't do battery re calibrating?
I've bought Bell one, I rooted already with djrbliss's motofail2go. Is this Bell's the international version? So, there is 4 AHD versions: AT&T, Bell, T-Mobile and the International?
And why Razr HD does already has recovery and AHD being older doesn't have?
You haven't been reading enough then. We have recovery also.

I don't believe there are T-Mobile and International versions.
As of this post there are AT&T and Bell variants. There is a Dev Edition coming "soon."
Does the Atrix HD get TMO 42MB/s HSPA+ or 21MB/s HSPA+?

Hi Everyone -
AT&T finally gave me the unlock code for my Galaxy Note 3 SM-N900A phone. I'd like the move it to T-Mobile, but have some questions before I do:
1. Is there any way to flash the T-Mobile/N900T firmware to an AT&T N900A variant? I'm talking the official factory firmware...CSC, bootloader, radio, everything needed to essentially do a complete conversion. I'm not interested in custom ROMs based on T-Mobile's firmware and that kind of thing. I assume if there is a way, it's not as simple as flashing N900T firmware in ODIN, since it would probably fail the model checks.
2. Is there any way of enabling the 1700 MHz AWS band for HSPA+ on an N900A? I know it works fine on T-Mobile LTE and will also work on HSPA+ in areas where T-Mobile has refarmed it for 1,900 MHz. I assume the 1,700 MHz lockout on the AT&T version is probably a software limitation inside the modem firmware.
If anyone can shed some light on this, I'd appreciate it.
Thanks!

You can't flash them or you would get hard brick. If that were the case people would have already unlocked their BL's using T-Mobile

I wonder why it would hard brick though. With the exception of atts bl being locked, wouldn't it all be relatively the same? Would it be possible to clean up the n900T bl to match the n900a?

Make sure you pay attention to the Modificatinator file and add the T-Mobile carrier file after installation. Works fine and much better than stock ATT junk rom.
Quick question to everybody on here... Is it possible to ODIN the baseband/modem for N900A to the N900T? I want to do this because my service provider is Cricket, which is an MVNO of AT&T. It's not a priority, but is it possible?

Probably, and if it doesn't work you can Odin the stock NC2 or NL1 firmwware back and start again with this ROM.
But why? If you're getting LTE the way your phone is (assuming Cricket is giving you LTE), you won't gain anything by flashing a different modem. (Unless you're getting a lot less signal with this ROM than you were with the NC2 or NL1 modems.)
Specifically the SM-N960UZPAXAA model that I'm looking at on eBay. I have clicked on numerous links that say it doesn't have both of these bands or only band 66.
The phone will be on the Metropcs mvno which uses T-Mobile.

Yes. All the N960U and N960U1 devices are the same exact hardware. They all support band 66 and 71. For the best coverage and support on Metro PCS, you'll need to either be running the U1 firmware or the T-Mobile firmware.

Thanks for the reply! I don't have much experience using Samsung devices and I heard you can't root the snapdragon models; so is it just a simple flashing of the firmware? If I don't run the firmware, will all the LTE bands still be available to me?

1. Correct, you can NOT root the US Snapdragon models.
2. Yes, you can flash any U or U1 firmware through ODIN without root or tripping Knox.
3. As far as I know you will have all bands available to you, though some people have said they get better coverage and signal on T-Mo after flashing the actual T-Mo firmware.
I'm currently running the U1 firmware on an unlocked ATT Note 9 and using it on the T-Mobile network without any issues.

There are a few threads with instructions on how to flash to the U1 firmware from the U or W firmware. Flashing to the U1 or W firmware will not SIM unlock your device from the carrier it is locked to though. It is highly recommended that you SIM unlock your device first, if you plan on switching carriers. For example, T-Mobile uses an app that is included to unlock devices sold by them.
According to this link, the T-mobile variant of the S10 only supports the necessary bands used for T-mobile, (B2(1900), B4(AWS), B5(850), B12(700), B66(AWS-3), B71(600MHz))
I know that T-mobile lets you unlock your phone under some conditions, so if I where to unlock it, would I get all the necessary bands used on other US carriers?
EDIT: Here's that link https://www.techwalls.com/samsung-galaxy-s10-model-number-sm-g973-differences/
That's SIM unlock, which is unrelated to activated bands. You'd need to access the service menu to see a list of all bands present. Although, one could flash the firmware of their desired carrier and gain access to features on previous generations.
Previous US models were able to access the required bands if the CSC and firmware were updated to the new carrier (I know from the S7 and S8. I cannot speak for the S10 though.

Yes, that is correct.
Here is a link to the process for the S8+ just to give you an idea of what it will be like, but keep in mind, these are NOT the instructions you will follow, it's just for reference.

I've been thinking about buying a Chinese model, or any unlocked snapdragon model. Since they have the same chipset, do you think I could gain the necessary bands for a US carrier? For example, I dont think they support band 71 out of box. Im wondering if since they probably use the same modem, if it would be easy to somehow unlock those bands through firmware

Unfortunately, I am not sure if you can flash the US Snapdragon firmware onto the Chinese model. In theory, it sounds possible.
Hi,
Does anyone know which bands are enabled on the US Cellular v405ua firmware? I currently have the 20a QA firmware flashed which has pretty much all bands enabled, but there haven't been any updates to it. I was thinking about flashing the US Cellular 20e version, but am not willing to lose any bands.

If you did OTA, i assume you are running stock? Not sure that helps me. Looks like att specific bands are disabled on the lg 40 from us cellular. Looks like i'm stuck with the 20a qa7 firmware for now.
